Furthermore, Tregs (regulatory T cells) from CIBERSORT, CAFs (cancer-associated fibroblasts) from EPIC, and NK cells from QUANTISEQ, as well as CD4+ Tem cells, epithelial cells, mesenchymal stem cells (MSCs), mv endothelial cells, neurons, natural killer T cells (NKTs), plasma cells, and smooth muscle cells from the xCell algorithm, were identified. The gene discussed is CD4; the disease is cancer.
